She is enigmatic, and symbolised by wisdom and the Sorcerer class. Despite her youthful and innocent appearance before the Cataclysm, wise Lumiel understood the nature and essence of Aether better than anybody. Her ability to channel it is still unparalleled, and as a result, she has the strongest magical power in all Atreia.
Before the Cataclysm, she was curious, innocent, and mischievous. In the centuries since, she has withdrawn and become something of a mysterious figure.
